Center Marker for Pipes & Tubes (15–30mm and 30–50mm)

Center Marker for Pipes & Tubes (15–30mm and 30–50mm)

Simple center-marking tool for round pipe, square tube, and similar stock. Slide it over your workpiece, twist until both guide pins contact the sides, then use the center hole to mark the exact midpoint with a pen or scribe. Great for finding the center on tube ends or along a workpiece for drilling and layout.

Includes two sizes:

15–30mm version – ideal for smaller pipes/tubes and better for marking ends where a tighter fit helps it lock in place.

30–50mm version – covers larger sizes, and also works across the full 15–50mm range, though it takes up more space on smaller stock.

Simple, fast, no-measure center finder for workshop use.
